Here’s my estimate of the IQ of the smartest person in various races, based on the average IQ and population size. All IQs are on a scale where British and American whites have a mean of 100 (standard deviation = 15). Because of lack of precise data, I assumed a normal distribution and a standard deviation of 15 for all races, though these assumptions are surely wrong in some cases:

group average iq estimated average genetic iq population size assumed standard deviation highest iq highest genetic iq
